Zhongyi Xie baa5302447 Avoid double-compacting data in bottom level in manual compactions (#5138) ... Summary: Depending on the config, manual compaction (leveled compaction style) does following compactions: L0->L1 L1->L2 ... Ln-1 -> Ln Ln -> Ln The final Ln -> Ln compaction is partly unnecessary as it recompacts all the files that were just generated by the Ln-1 -> Ln. We should avoid recompacting such files. This rule should be applied to Lmax only.
